What they are
CapCut
CapCut is a free video editor built for short-form content, covering trimming, transitions, captions, and AI-generated effects across mobile and desktop. It is the go-to tool for TikTok creators, though ByteDance owns it, which is a real consideration for creators concerned about data privacy or platform risk. The free tier is generous, and a Pro subscription unlocks additional assets and AI features.
Stable Diffusion
Stable Diffusion is Stability AI's family of open-weight text-to-image models, covering everything from the widely adopted SD 1.5 and SDXL to the current SD 3.5 series. Developers access it via a credit-based API, while creators with capable hardware can run it locally for free under the Community License. It spans image generation, editing, upscaling, style transfer, 3D asset creation, and audio generation. The ecosystem of community fine-tunes, LoRAs, and third-party UIs is unmatched, but that depth comes with a real learning curve.
